We are getting closer to shooting the cab, after some slow downs in the schedule.
Accordingly, we needed to finish any fabbing/welding that involved the cab, so it was time to buy the airbox and figure out how to support the weight. We searched high and low for pix/or info as to how others had done this but came up dry. So we engineered our own system. We needed to be careful to have adequate strength, especially since the sheet metal of the cab is so very thin, much of it being only 22 ga. We did not want the airbox bouncing around on a mount as we went down the road and crack out any of the tin of the cab. We fabbed a bracket that went from A pillar to A pillar, and made a separate center support by welding a 5/16" bolt to a 2"x2" pad and then plug welding that to the center of the firewall. The bracket is 1/8" x 1.5" flat stock.
Only a small portion of the evap will hang below the dash. The glove box space will be reduced but this is Texas, so A/C trumps glove box any day of the week. This is an evap with heat/defrost capability made by Old Air, Ft Worth, TX.
I have often wished there were some other M5 owners around here that I could compare notes with. Sometimes it seems that I am in the middle of a very large deserted field with no one within sight for miles and miles!
